CalenGoo gives you a fast and easy way to access and modify your Google Calendar with your iPhone, iPod Touch or iPad. It can also be used when you have no Internet connection, using the cached data. Changes are saved and uploaded the next time you are connected. The calendar view is similar to the web view of Google Calendar. Events are displayed using the same calendar colors that you use in your Google Calendar, even Google's event colors are supported (please see http://www.calengoo.com/cc). It also recognizes which calendars are visible and which are hidden. So the view should match the view of your Google Calendar as much as possible. CalenGoo also has a month view similar to that of Google Calendar. It can be zoomed and panned to quickly get an overview over the events of a month. Zooming the month is done by using the two-finger-zoom gesture that you know from Safari and the photo application. A double tap opens the tapped day. It also supports the same kinds of recurrence rules as Google Calendar and displays recurring events correctly even when you are offline or scroll far into the future. You can also use Google Calendar's feature to invite people to events and see their status (accepted, declined, maybe, no answer). They will get an invitation email with links to e.g. accept or decline the invitation. Google Calendar has an integrated task list, called Google Tasks. Tasks with a due date are displayed on the corresponding days of the calendar. CalenGoo can do the same, it can sync this list, display your tasks in the calendar views and in a list view and it even makes your tasks available offline. You can edit and add tasks and the changes will be synced with Google Tasks. You either need a (free) Google Calendar account to use this app or you can use it with your iOS calendars (just tap the gear icon in the login screen). However using it with Google Calendar has several advantages. If you have problems to log in with CalenGoo, please make sure that at least one event is in your Google calendar. To get more information, screenshots and a tutorial, please go to http://www.calengoo.com. If you have any problems or suggestions, please send an email to calengoo@dgunia.de. It is technically impossible to reply to reviews, you need to write an email or take a look at CalenGoo's support website to get help. If you think the font is too small and hard to read, you can increase the font size of all calendar views in the settings under "Settings", "Display and Use".
